Hello anybody out there. I have two salt water tanks setup. One of them is a regular 20 gallon. There are two filters on it. One of them is a Penguin Bio-Wheel 200 with a regular charcoal filter in it. I put in a ChemiPure Elite half unit in it. The other filter is a Topfin 10. The other tank is a 38 gallon Innovative Marine with one unit of ChemiPure Elite. Both tanks have live rocks and live sand. They both finished their recycle periods. Everything is checked out fine. So My question is, which tank is better to keep Sunburst seahorses and a pair of pine fish that you have? Is the 20 gallon tank with two filters too much for them? Should I just keep the big filter on and not the little filter? Is that enough filtering power for them? In the 38 gallon tank, do you think the current is too strong for them? I cannot adjust the strength of the filter even though the tank has plenty of space for them. Please let me know which tank is best for them. If you think the 20 gallon is best for them, how many Sunburst seahorses can I keep in there? If you think the 38 gallon is best, can you also let me know how many of them I should keep in there? Thank you very much.
